\u010cistilnik, ki po obliki spominja na tovarni\u0161ki dimnik, namesto \u010drnega strupenega dima v okolico izpu\u0161\u010da pre\u010di\u0161\u010den zrak, poro\u010da francoska tiskovna agencija AFP. Dnevno lahko o\u010disti od pet do 18 milijonov kubi\u010dnih metrov zraka, odvisno od vremena, letnega \u010dasa in stopnje onesna\u017eenosti.<\/p>\n

\u010cistilnik, katerega izgradnja je stala dva milijona dolarjev, zmanj\u0161uje koli\u010dino zdravju zelo nevarnih trdih delcev PM 2,5. Njihovo gostoto lahko zni\u017ea za od 10 do 19 odstotkov.<\/p>\n

Sistem deluje tako, da stolp s pomo\u010djo son\u010dne energije vsesava onesna\u017een zrak iz okolice, ga pre\u010disti skozi filtre in nato v okolico izpusti \u010dist zrak.<\/p>\n

Umazan zrak gre najprej v posebne “tople grede” s steklenim stropom, name\u0161\u010dene ob vzno\u017eju stolpa. Te se razprostirajo na povr\u0161ini, veliki pribli\u017eno za polovico nogometnega igri\u0161\u010da. Topel zrak se nato v stolpu dviguje in pri tem potuje skozi ve\u010d plasti \u010distilnih filtrov.<\/p>\n

\u010cistilnik poskusno deluje od lani in znanstveniki na Institutu za okolje Kitajske akademije znanosti, ki ga testirajo, so z rezultati doslej zelo zadovoljni, saj se je kakovost zraka na obmo\u010dju ob\u010dutno izbolj\u0161ala, je na svoji spletni strani poro\u010dal South China Morning Post.<\/p>\n

Kot je dejal vodja raziskave na omenjenem institutu Cao Junji, so izbolj\u0161anje kakovosti zraka zabele\u017eili na obmo\u010dju v okolici \u010distilnika, velikem okoli deset kvadratnih kilometrov.<\/p>\n

Po njegovih besedah je ob dnevih, ko je bilo onesna\u017eenje \u0161e posebej hudo, zni\u017eal koli\u010dino smoga na skoraj zmerno raven. \u010ce se bo v poskusni dobi izkazal za uspe\u0161nega, pa nameravajo tak\u0161ne stolpe namestiti \u0161e drugod na Kitajskem.<\/p>\n

Da bi o\u010distili ozra\u010dje v mestu, ki se razprostira na povr\u0161ini tiso\u010d kvadratnih kilometrov, bi sicer potrebovali okoli sto tak\u0161nih stolpov, je pojasnil Cao, ki naj bi v kratkem objavil rezultate testiranj \u010distilnika.<\/p>\n

\u0160tevilni so dvomili v u\u010dinkovitost naprave. “Tudi sam sem bil v dvomih, a ko smo kon\u010dali, so bili rezultati precej dobri. Dosegli so na\u0161a pri\u010dakovanja,” je \u0161e dejal Cao.<\/p>\n

Kitajska vlada je leta 2014 napovedala vojno onesna\u017eenju ozra\u010dja in okoljsko ministrstvo je za 28 mest na tem podro\u010dju postavilo stroge ukrepe. Najmanj trije milijoni domov, kjer se grejejo na premog, naj bi tako pre\u0161li na elektri\u010dno gretje.<\/p>\n

Kakovost zraka v dr\u017eavi se je lani nekoliko izbolj\u0161ala. Povpre\u010dni dele\u017e delcev PM 2,5 v orza\u010dju je tako v 338 mestih padel za 6,5 odstotka, dodaja AFP.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
